GUARD FOR VARIETY MOLDERS.

SPECIFICATION forming part of Letters Patent No. 260,974, dated July 11,1882.

Application filed April '26, 1882.

To all whom it may concern;

Be it known that I, GOTTFRIED GRILL, of Baltimore city, State ofMaryland, have in: vented certain new and useful Improvements in Guardsfor Variety Molders; and I hereby declare the same to be fully, clearly,and exactly described, as follows, reference being had to theaccompanying drawings, in which Figure 1 is a top plan, and Fig. 2 is aside elevation, of the device.

My invention relates to guards or shields adapted to be used inconnection with variety molders, and designed to prevent injury to theoperator by rendering it impossible, in the ordinary use of the machine,to bring the hand within the range of the out f the knives; and itconsists in a guard constructed and operating as hereinafter set forth,the points of novelty being made the subject of the claim.

In the drawings, A is the table, through which projects thespindle at,having knives a, secured, as usual, byrings h", collars h, and a nut, B.Close by the side of the spindle a rod, 1), is mounted on the table, andserves as a standard or support for the guard F. This latter isbell-shaped, as shown, and is provided with a number of slots, ff,through which the operation of the cutters may be observed. The end F ofthe guard is slotted for the passage of the rod b, on which is mountedone or more rings, 0, which serve to support the guard at the properheight. The slotted end F admits of an adjustment of the guard to orfrom the spindle in the line of the slot, a nut, 0, serving to clamp theguard tightly on the rod b. A plate, 0, attached to the guard at e, andhaving a slotted end, 0, corresponding to the end F, is clamped to theguard by the nut O.

D is a plate terminating in a ring, d, which embraces the spindle a, andhaving a longitudinal slot, 61, at the opposite end, where it isadjustably clamped to the plate cby a thumbscrew, E.

In operation, the cutters being secured upon the spindle, the guard isplaced in position, as shown, the ring 01 embracing the spindle. Asuflicient number of rings or washers, c, is placed on the rod b tosustain the guard at the desired height, when it is adjusted to or fromthe spindle, by sliding the guard on the rod 1) and swinging it aboutthe same as a pivot.

(No model.)

When adjusted the nut G and screw E are tightened, securing the guard inplace, the arm D preventing the guard from approaching the spindleshould the nutO jar loose. Being located close beside the spindle, therod 6 does not interfere with a class of work that has heretoforenecessitated the temporary removal of guards. I refer to inside work,such as heading the inside edges of door-panels. A panel is rarely sonarrow as not to embrace both spindle and rod. The progress of the workmay be observed through the slots, while the guard prevents the hands ofthe operator from approaching too near the knives. My device is adaptedfor use with the ordinary molder, and is also adapted for use in allordinary kinds of work. This is very important. A guard which must beremoved every now and then is worse than none, for the very end designedto be obtained is defeated. A workman who knows that there is a barrierbetween his fingers and the knives will not be so careful as if thatwere not the case, and when one once accustomed to rely on the guard iscompellcd to work temporarily without it he is almost sure to be cut.

Were it possible,by the exercise of the great est care and vigilance, toavoid accident in running the variety molder, a guard which under anypossible conditions could not be used would be a bad thing, for theincreased dangerol accident when it is not used would outweigh all its.advantages when in use; but as a matter of fact accident is only aquestion of time with the molder. The most careful workman is nearly aslikely to be hurt as a beginner, so I have devised the guardhereinbefore described for the protection of both, constructing andarranging it in such manner as to enable it to be used always.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In combination with the spindle and rod b, the bell-shaped slot-tedguard and plate 0, and the arm D, having at one end a ring whichembraces the spindle, and is adjustably secured to the plate 0 at theother, as set forth.

GOTTFRIED GRILL.
